J. MGDONALD ET AL LIQUID FUEL F'URNACE Filed Feb. 6 1923 Sheets-Sheet 2 between the furnace and eces122 to co-operete respectively with the -stops 18 and 21.

With the stop 18 set and secured in epredetermined position, as for instance indi.- ceted in Fig. 5, vthe lever 17 een he swung around into contact therewith, to thereby ro tate the ring 7v into a position where its ports 10 will co-operute with'the ports to pro vide the desired clearances for air admission. Hence the operator is required to merely swing lever 17 around to thelimit of its movement to enable n proportionate pressure of oir, commensurate' withe desired quen- 'tity of liquid fuel, for' the production of e predetermined, lproportionate iniidzureI of liquid fuel'and air.

The ring 7 is cestv in several sections for1 convenience, also because, when one set ci teeth 9 becomes worn, the ring may loeshift ed to bring another seztot teethvinto cc-operetion with pinion 14,

A structural feature of' improvement alie-y closed in this applicstionconsists of the sn.- giilerly disposed, an'iiulerienge 23, secured to the .inner surface of beck plete 3, enel serving to confine certin heet insiiletionv ma.;

. in the lute gen ample opening 25, which is norma ly closed by the upper and lower -dooi's 26, 27, .these doors beinghingled i'esi'iectively at 28 und 29 so that the door`26 opens by swinging downwardly, and the door 27 opens by heine,r swung upwardly.

vPivotal handles 30,` 30, mounted in the ydoors 26, 2?, each have an inner latch portion 31 to engage the inner surfiice of Wall 2 for locking the doors when shut.

The upper door` when opened, will stay open by gravity. But the lower door, which opens upwardly, is held open by means of a, pivotal latch 32, mounted on the plate 2, and iiilu )led to he turned to engage the rear edge when 'the lutter is open. Variations within the spirit und scope of our invention :ire equally coinpichended by the foregoing disclosure.
